Definitions

  • the present invention relates to a slit dilating device and a method for dilating the slit. More particularly, the present invention relates to a slit dilating device for dilating a slit for various purposes including insertion of graft, extraction of graft, surgery, food container, beverage can or the like.
  • Forceps usually include two arms fused together at an end or joined with a spring mechanism.
  • the fused joint or spring mechanism causes inhibited motion of the arms of the forceps.
  • movement of the arms with respect to each other is resisted until a force is applied to the forceps to overcome the resistive force of the spring mechanism or fused joint.
  • a user must constantly apply pressure or force to the arms to retain the altered position of the arms with respect to each other.
  • a user must maintain pressure on the forceps to control the forceps while applying pressure to the forceps to retain an object. Accordingly continuous use of forceps in such medical treatment causes fatigue to the human finger and hand muscles especially during hair implantation procedure, which lasts for several hours as per the cases.
  • the finger grip facilitates movement and/or control of an arm of a forceps by a user.
  • a user may only need to apply pressure to the forceps to grip an object and not to retain the forceps in the user's hand since the finger grips would inhibit the forceps from being dropped by the user.
  • the forceps though creates ease in use as compared to the conventional forceps, however, still results in fatigue to the human muscles due to continuous application of pressure or force by the fingers to grip the object during the medical procedures.
  • One embodiment of the present invention discloses a slit dilating device comprising of a shaft including a hook configured to dilate a slit. At least a finger grip positioned on said shaft and configured to grip a finger of a user. The finger of the user gripped in the finger grip moves the shaft radially to the slit thereby dilating the slit by the hook.
  • This device uses two finger grips, which are positioned on the surface of the shaft to grip the finger of the user in the finger grip, thereby increasing the gripping of the finger in the finger grip.
  • the surface of the shaft faces the finger grip thereby providing support to a lower surface of said finger for efficient working of the device and avoiding fatigue to the human muscles especially during longer medical procedures.
  • the finger grip includes an adjusting structure, which is configured to adjust the finger grip thereby gripping the finger of said user properly.
  • Another embodiment of the present invention discloses a method of dilating a slit comprising the steps of gripping a finger of a user in at least a finger grip positioned on a shaft by a hook and dilating the slit by the hook connected to the shaft by moving the shaft by the finger of the user gripped in the finger grip radially to the slit thereby resulting in efficiently inserting the graft in the slit without causing damage to the graft and avoiding excessive bleeding during implantation.
  • the method includes gripping the finger in two finger grips and supporting a lower surface of the finger by a surface of the shaft facing the finger grip, thereby achieving the speed during implantation or other medical procedure and avoiding the excessive bleeding during such procedures.
  • the method also includes adjusting the finger grip by an adjusting structure thereby gripping said finger in said finger grip for increasing gripping and avoiding unnecessary movement of the device during procedures.
  • the application of the device efficiently allows the user to control the pulling force or grasping force during the extraction of the graft without causing fatigue to the user's skin.
  • the device also provides an adequate or efficient stretch to the scalp and the skin by traction and counter traction of the surface of the skin or scalp for making cut or slit for implantation or extraction of the graft.
  • Figure 1 discloses an embodiment of the present invention depicting isometric view of the slit dilating device with finger grip.
  • Figure 2 discloses an embodiment of the present invention depicting isometric view of the slit dilating device with the finger of the user.
  • Figure 3 discloses an embodiment of the present invention depicting the method of hair implantation with slit dilating device.
  • a slit dilating device comprising of a shaft (12) including a hook (18) and a fmger ring (22).
  • the shaft (12) also includes a surface (14) and a terminal (16) on which the finger grip (22) and a hook (18) are positioned respectively.
  • the hook (18) is configured to dilate the slit (26) in order to implant the graft (28).
  • the shaft (12) is a lengthwise structure with a surface (14) on which the fmger (20) of the user rests on during the use of the device.
  • the surface (14) facing the finger grip (22) supports the lower surface of the finger (20) of the user.
  • the surface (14) has two finger grips (22) positioned in a way to grip the finger completely.
  • One of the finger grips (22) is positioned close to the terminal (16) and the other is positioned away from the terminal (16) in way to keep sufficient distance between the finger grips (22) to have sufficient gripping on the device.
  • These finger grips (22) include an adjusting structure (24), which is configured to adjust the finger grip (22) as per the size of the finger (20) of the user.
  • the index finger of the left hand of the user is inserted into the finger grips, which is configured to grip the finger and then the adjusting structure (24) is adjusted accordingly so that the finger (20) is properly placed in the finger grip (22) and the user can comfortably use the device without losing the grip on the device.
  • the adjusting structure (24) can be a screw, which can be loosen and tighten by the screwdriver.
  • the recipient is prepared prior to the process of the hair implantation by forming the premade skin slit on the head.
  • the grafts (28) are prepared separately for the implantation on the recipient, which is performed by the implantation device (30).
  • the implantation device (30) can be a medical forcep to hold and implant the graft (28) in the respective slit (26).
  • the slit dilating device dilates the slit (26) in order to insert the graft (28).
  • the user wears the device on the index finger of the left hand by inserting the finger (20) i.e. the index finger into the finger grips (22) followed by adjusting the adjusting structure (24) to have sufficient grip on the device.
  • the hook (18) at the terminal (16) of the shaft (12) is placed either inside the slit (26) or on the top layer of the slit (26) in a way to connect the side surface of the superficial skin layer.
  • the finger (20) gripped into the finger grips (22) is then moved relative to the slit (26) or radially to the slit (26) i.e. the shaft (12) is moved in a way to pull the sides of the slit (26) gently by the hook (18) of the shaft (12), thereby dilating the opening of the slit (26).
  • the user implants the graft (28) into the slit (26) by the implantation device (30). Once the graft (28) is implanted, the user moves the finger (20) gripped into the finger grip (22) again i.e.
  • the shaft (12) is moved radially towards the slit (26), thereby gently releasing the sides of the slit (26) from the hook (18) and contracting the slit (26).
  • the adjusting structure (24) can be ring or circular structure made of flexible materials to hold the finger (20) and provide sufficient grip to use the device.
  • the surface (14) of the shaft (12) facing the finger grip (22) is flat there by providing further support to the finger (20) of the user.
  • the device (10) dilates the slit of the scalp during extraction of the graft or separation of already cut hair follicles or during collection of follicles.
